How do does radio signal keep on travelling in space? Shouldn’t it just fade away.
In: Engineering
It’s because it travels through electromagnetic waves that permeates the universe, it’s not like sound waves that need a physical interaction to travel from one place to another.
But, you are on the right track, because on larger distances other electromagnetic sources interfere with the original signal and they tend to “wash up” instead of keeping the initial properties of the signal
